A bivalent of meiosis 1 consists of
- A four chromatids and two centromeres
- B two chromatids and one centromere
- C two chromatids and two centromeres
- D four chromatids and four centromeres
Answer & Solution
Correct Answer
(A) four chromatids and two centromeres
Step-by-step Solution
Detailed explanation
(A) four chromatids and two centromeres,
In the first prophase of meiosis 1, a bivalent formed through the pairing of homologous chromosomes, each with two chromatids. This results in a structure with four chromatids and two centromeres (one for each homologous chromosome).
